The term showroom usually implies an entertainment venue
connected with a casino, hotel, or resort. A showroom may
be designed to accommodate variety or headliner acts,
or it may be purpose-built for a specific production, such
as a circus show, that will reside in the space for years or
even decades. A smaller room may seat only 600, but seat
count is more often in the range of 1,200 to 4,000 seats.
The theatre may take the form of a proscenium, thrust, or
arena stage. Showrooms may introduce elaborate stage
machinery, including “water stages” and other specialty
mechanics.
